Function description
How it works
LEAKPEN is an acoustic measure-
ment device. A vibraphone picks up
noises from the water pipes under
inspection. The measurement results
are shown numerically on the display
and transmitted acoustically through
headphones.
The measurement device and head-
phones can be connected via Blue-
tooth or with a cable.
The loudest noises reveal the location
of the leak. Extraneous noises can be
cancelled using high- and low-pass
filters.
Either disposable batteries or re-
chargeable batteries can be used to
power the measurement device.
Preparations
Setting up the power supply
The measurement device can be
operated by means of disposable
batteries/rechargeable batteries.
For permissible types, see Technical
specifications.
CAUTION
Damage to electronic components .
Incorrect set-up of the power supply
for the measurement device can
cause damage to electronic compo-
nents and other parts of the device.

Preparing the working area
In order to achieve optimum and relia-
ble measurement results:
–
The working area should be free
from dirt and contamination.
Check the measuring point and vi-
braphone and clean as necessary.
–
There must be enough space
in the working area around the
measuring point to allow the vibra-
phone to be positioned correctly
with respect to/properly connect-
ed to the area under inspection.
Check whether there is enough
space and adjust if necessary.
–
There must be enough space in the
operator's working area in order to
guarantee safe, optimum operation
of the measurement device.
